A family court judge heard either Pyke or Rytting had assaulted tragic Poppy

He continued: "Part of the assault involved Poppy being subjected to a shaking or shaking impact type event. The consequence was Poppy went into respiratory arrest, then cardiac arrest, then she lost her life.

"Whether (she died as a result of) a blow to the head or shaking event matters not.

"She died as a result of the assault."

Judge Heaton added: "I unhesitatingly conclude that both know far more about how Poppy lost her life than either of them are prepared to say.

"The mother and Mr Rytting are seeking to conceal from view what happened in the flat that morning in order to protect themselves."

Judge Jeremy Richardson said the pair were living in a swamp of drug addiction

He continued: "It's not possible to say whether the mother acted alone or Rytting alone or whether they were both involved and what role each played.

"I am entirely satisfied, however, to the appropriate standard of proof that both knew what happened in the flat that morning.

"Having reflected carefully on the matter, I have come to the conclusion I can't identify either of the two adults as the perpetrator of this traumatic event."

Michala Pyke denies two offences of cruelty towards Poppy while responsible for her

The CPS has said they could not charge Pyke or Rytting on manslaughter or murder grounds due to lack of evidence.

PS senior district Crown prosecutor Catherine Ainsworth said: "The reason the CPS did not charge these two defendants with murder or manslaughter was because the experts were unable to ascertain a clear cause of death.

"The experts were able to agree, however, that the drugs did not contribute to Poppy's death.

"Therefore there was insufficient evidence to prove to the high standard required in the criminal courts that the neglect Poppy suffered contributed directly to her death."
